WINDOW VENTILATOR.

Application filed April 14, 1921.

rlhis invention relates to window ventilators of the type wherein adetlector is located upon the window sill, at the inner side of theroom, opposite to the lower window sash, and the latter is 'partiallyopened; whereby the air enters and strikes the detlector, which directsit upwardly, and the incoming current is in this manner spread over theentire room gradually and evenly, and also uniformly, without causingany draft which is injurious to the occupants.

' The principal object of my invention 1s to provide an improvedventilator of this type, which is simple, inexpensive, conveniently andeconomically manutacturable, convenient and economical of installationby the vuser without requiring any skill, con veniently utilizable,strong, rigid and durable, and which when in use may be readily andconveniently detached entirely from its place by the user, andreattached by him when it is desired to return it to its operativeposition.

Another object oit' the invention is to pro-.

vide a ventilator ot' this type, which is entirely manutacturable andcapable of being litted to any width ot window, `without requiring anyspecial work or any kind of reconstruction of any part thereof.

Other objects and advantages will hereinafter appear.

In the accompanying drawings,-`

Fig. l is a vertical section ot the ventilator, showing it in installedoperative state.

Fig. 2 is a plan view of the ventilator, shown in Fig. 1, the same beingshown as partially broken away.

Fig. 3 shows a detail of the ventilator.

Fig. 4 is a front elevation ot the ventilator shown in Fig. 1.

Figs. 5, 6, 7, 8 and 9 show details of the ventilator.

Upon the sill l is positioned a deflector 2 which is adapted to swing,in the manner hereinafter described, toward and away from the lower sash3 of the window 4. To each side of the window-fra1ne 5 is secured afitting 6 by means of wood-screws 7, and Y to each fitting is joined asection 8 of a sidebracket 9, which brackets carry the deflector 2. Theiitting 6 is provided with a pair of stamped out flanges 10, Figs. 5, 6,7,that

comprise central circular portions 11 with elongated bars 12 extendingtherefrom in 55 opposite directions, and each section 8 is provided witha pair of openings 13 that are Serial No. 461,197.

of a similar configuration and slightly larger in area. When it isdesired to join the section 8 to the litting 6, it simply requiresinsertion of the flanges l0 ot the fitting into the openings 13 oit thesection 3 and dropping the latter downwardly, whereupon the circularportions 11 of fianges 10 pass through the openings 13 of sections 8 andbecome positioned behind the narrow parts ot said openings and in thismanner lock the sections 6 securely to the fittings 6. To the corner lllof each section 8 is pivoted a pair of triangular sections 15, 16forming part of the bracket 9, and the deflector 2 is directly joined tothe section 16. The corners of the bracket-section 15, are provided withprojections 18 which are bent over the upper rims of sections 8, 16, inthe manner shown, whereby those projections abut against extensions 17formed at the corners ci' the sections 8, 16 and in this manner hold thesections to each other, guide the sections 15, 16 when the are swungabout their pivot 111 and limit the swinging movement of sections 15, 16about their pivot 141. The brackets 9 thus consist of the sections 8,15, 16 which spread out or open up in fan-like manner about their commonpivotvlll, and which may be folded up or closed until the three sectionsoverlap each other, and as these sections are opened and closed thedeitlector 2, which is joined to the section 16, is thereby similarlyswung about the pivot 14, toward and away from the lower window-sash 3,from the inclined position shown to a vertical position and baokwardy.Said deiiector comprises a pair of angular frames 19, which telescopeeach other, Fig. 3, and between which is mounted aglass pane 2O that isheld in place laterally by means of bolts 21 which pass through saidtrames to secure them to each other, together with the pane 20. Thebolts 21 are tightened by means ot' nuts 22 which thread thereover andare provided with en larged heads 23 and shanks 211 ot reduced diameter.The bracket sections 16 are provided with bent portions or rails 25having keyhole shaped openings Q6, each comprising a circular part 27and a narrow elongated part 28. llfhen it is desired to mount thedeliector 2 in operative place, it merely requires passing the heads 23of nuts 22 through the circular parts 27 of the openings 26, and thensufliciently lowering the deiiector to permit the shanks 211 to passthrough 4the parts 28 of said "openings, with the heads 2310i the nutspositioned behind the rails 25, as shown'in Figs. 1, 2. A link 29 ispivoted at 8O to the bracket-section 16, a similar link 31 is pivoted at32 to the section 8, and a Vthumb-screw 33 passes through the extremityof link 29 and threads into the 'extremity of link 81, whereby looseningot the thumb-screw 33 permits free pivoting of the' links labouttheshank oi' said screw, while 'tightening o'i' the thumb-screw lockshe'two links to each other, and inthis manner the deilector 2 may belocked in any desired position. Thus, the dei-lector may be swung andset to an extreme inclined or open position, to admit a maximum of airand ventilation, orit may be set to a vertical or extreme closedposition for minimum ventilation in stormy or cold weather, or it may heSet to any intermediate inclined position, as shown, and `upontightening` ot' the thumb-screw 33 the deflector may be locked in anyposition to 'which it has been set. Adjacent 'to the window sash 3 islocated a screen '34 which rests upon the sill 1 and serves to prevententering ot dust, insects, etc., into the room during the ventilation.The fitting 6 is provided with a bent L-shaped tongue 35, and the trame36 of said screen is provided with a channelled groove 37,-and in orderto `mount the screen in proper position it merely -requires lowering ofthe `same in such manner that the tongue 35 of itting 6 passes throughthe groove 37 of the screen, as shown in Fig. 2.

All that is required to install the ventilator, therefore, is to securethe fitting `6 in place Vby its screws 7, then placing the brackets 9 inposition by means of interlocking its openings 13 with the flanges 110ithe littings, and then mounting the detlector 2 in position by means ofinterlocking its nuts 22 with the openings 26 of the -rail 25 oi'bracket-section 16, and Vthese operations can be easily executedpersonally by any purchaser ot' this ventilator without requiring skillor-any help. lt will be also evident that to temporarily remove theVventilator, during vwa-rm weather or for window repairs, all that isnecessary is demounting the deiiector 2 by merely lifting it slightlyand withdrawing it from the bracket rail 25, then removing-the brackets9 by simply lifting each of them slightly and withdrawing it from thetting '6, and then the screen 34 may be removed by elevating it upwardlyand thereby disengaging it completely from the fitting 6. lhen it isdesired to replace the ventilator the same is easily performed byrepeating these operationsrin an opposite order and manner.

In the manufacture vof this ventilator, the Y deflectors 2 and screens34 are made of lengths so as 'to it the ventilator to windows the widthsof which are 20, 25, 30, 35,

etc., as these are the most common dimensions for window widths. .Shouldit be necessary, however, to fit the ventilator to a window of specialwidth, such as 29 inches, the same can be accomplished by a pair offillers 38 and 39, Figs. 8, 9. Each of the fillers 38 is provided with abutton 4G, which button 40 interlocks .with the openings 26 of thebracket-rails 25, and the iiller is also provided with openings 41,similar to the openings 26, which openings 41 interlock with the nuts 22oi' the deflector 2. Each-of the fillers 39 is provided with -astamped-.out portion 42 which interlocks with openings 43 in thefittings 6, that are similar to the keyhole shaped opening 26, and theliller is provided 1with an YL-shaped extremity 44 adapted to passthrough thegroove 3.7 `of the screen. In order to 4install theventilator upon a window of this odd size, therefore, it

is only 4necessary to select pairs of 2 :inch ii-llers and 4interlockthese fillers 38, 89, with the rails 25 and fittings 6,.and ythen theregular detlector and screen adapted to tit a 25 inch window may be.mounted in the usual manner by interlocking them with the said fillers.Should the width of the window be a traction ot Ian inch over 29 inches,such as 291/2 inches, this condition can be remedied by inserting a l@inch piece of wood between each fitting-6 and the window-frame 5, 4andthen screwing the itting 6 in place. Fillers of various widths are thussupplied to provide for all windows .of various widths. If it is.desired to equip a window of unusual width, otabout inches and upwards,it is preferable `to utilize two deilectors and two screens, that areadapted for 30 inch windows, instead of using one special long delectorand one long screen for such special purpose. ln such case the twodeectors and two screens may be placed end to end, as shown in Figs. 8,9, straps 45, `46 may be placed .at each side of the joining extremitiesof the `delectors, and screws 47 may be then passed through the straps45, Fig. 8 and through the openings 48 intended for the bolts 21 and thescrews may be threaded in- Y to the straps 46. In a similar mannerscrews 47 may be passed lthrough the straps 45, Fig. 9, and openings 49in the screen and threaded into the straps 46.

It will be evident that this ventilator and every part thereof isentirely manufacturable and that no special work is necessary orequipping any window of any size, by which is meant kthat when an orderis received for a ventilator for a window o any width, all of the `partsconstituting the ventilator for such window may ybe vthereupon suppliedfor immediate installation, without requiring any special constructionor alteration whatever of the ventilator or any part thereof. Y

Variations may be resorted `to within the scope of the invention, andportions of the improvements may be used without others.

Having thus described my invention, I Claimz 1. A window ventilatorhaving the combination with side brackets, and a deiector, of-means forjoining the deiiector to said brackets including headed bolts, saidbrackets having slots adapted to receive said bolts and permit them todrop downwardly therethrough for mounting the defiector upon thebracket, said deflector comprising a pair oi' frames, a pane of glassfitted between said frames, and said bolts passing through said framesand securing them to each other.

2. A window ventilator having the combination of a fitting adapted to bepermanently secured to the window, aside bracket, a defiector, means tojoin said deiector to said bracket, means to attach said bracket to anddetach it from said fitting, said bracket having a guide, a screen, andsaid screen having a recess adapted to slide over` said guide andreceive the guide for joining the screen to said fitting.
